Effects Of Inorganic Nutrients And Dissolved Organic Carbon On Oxygen Demand In Select Rivers In Northern Utah, Joseph L. Crawford May 2013

Effects Of Inorganic Nutrients And Dissolved Organic Carbon On Oxygen Demand In Select Rivers In Northern Utah, Joseph L. Crawford

All Graduate Theses and Dissertations

Sewage, agricultural runoff, and atmospheric deposition have greatly increased the amount of nutrients (largely nitrogen (N) and phosphorus (P)) in surface water nationwide. Excess nutrients are associated with algal blooms and dissolved oxygen depletion in many water bodies, but linkages between nutrients and dissolved oxygen have been largely correlative. Biochemical oxygen demand (BOD) is a regulated water quality parameter that is aimed at describing the amount of oxygen consumed during the decomposition of organic matter. Despite the awareness that excess nutrients are linked to dissolved oxygen in rivers, few studies in the nutrient criteria literature discuss BOD measurements or how ...


Diet Composition And Activities Of Elk On Different Habitat Segments In The Lodgepole Pine Type , Uinta Mountains, Utah, William B. Collins May 1977

Diet Composition And Activities Of Elk On Different Habitat Segments In The Lodgepole Pine Type , Uinta Mountains, Utah, William B. Collins

All Graduate Theses and Dissertations

The biweekly diets of tame elk (Cervus canadensis nelsoni) were established on a species dry-weight basis for different habitat segments of the lodgepole pine (Pinus contorta) type, Principal species in the diets (5% or more) on each habitat segment were generally composed of preferred species. However, some highly abundant but non-preferred species took on principal dietary status, whereas some preferred species, scarce in the vegetation, contributed less than 5 percent to diets. Forbs contributed most to total consumption; grasses and sedges were the second largest contributors. Browse appeared to be of limited importance, but mushrooms had special significance in forested ...


Forage Preferences Of Mule Deer In The Lodgepole Pine Ecosystem, Ashley National Forest, Utah, Joseph A. Deschamp May 1977

Forage Preferences Of Mule Deer In The Lodgepole Pine Ecosystem, Ashley National Forest, Utah, Joseph A. Deschamp

All Graduate Theses and Dissertations

During the summer of 1976, five tame, trained mule deer (Odocoileus hemionus hemionus) were used to determine botanical composition and relative preference of mule deer diets on five habitat segments in the lodgepole pine (Pinus contorta) ecosystem of northeastern Utah. Diets were statistically analyzed according to estimated we1ghL consumption per unit of time spent feeding on the different segments. Habitat segments sampled were: clearcut forest, dry and wet meadow, mature forest, and stagnated forest. Diets differed between segments mainly because of differences in plant species available and their abundance. The diets in the non-forested segments averaged over 90 percent forbs ...


An Autecological Study Of Blackbrush (Coleogyne Ramosissima Torr.) In Southwestern Utah, James E. Bowns May 1973

An Autecological Study Of Blackbrush (Coleogyne Ramosissima Torr.) In Southwestern Utah, James E. Bowns

All Graduate Theses and Dissertations

The purpose of this study was to provide basic ecological information on an important but little studied major vegetation type through autecological investigations of the dominant species. Data include climate and soils where this species occurs, root distribution, phenology and growth, seed germination requirements and seedling survival. Percent ground cover provided by blackbrush and other dominant plants as well as the composition of herbaceous understory vegetation was presented. Leaf and stem anatomy of blackbrush revealed features typical of desert shrub species with stem splitting appearing to be a characteristic of this species.

Blackbrush is characterized as a poor forage species ...


Analysis Of Hunter Characteristics And Attitudes Relating To Utah Shooting Preserves, John T. Ratti May 1973

Analysis Of Hunter Characteristics And Attitudes Relating To Utah Shooting Preserves, John T. Ratti

All Graduate Theses and Dissertations

This paper evaluates the present status of Utah shooting preserves with special reference to attitudes and characteristics of hunters using and not using the shooting preserves system. Data were gathered primarily by a mail questionnaire survey.

Compared to non-users, shooting preserve users were more frequently raised in a suburban or city area, better educated, and had higher yearly incomes. Shooting preserve users were commonly employed as professionals or proprietors, while non-users were often employed as craftsmen, proprietors, or operators.

Most shooting preserve hunters hunted after the state game bird season was closed, and were generally satisfied with Utah preserves. Most ...


Primary Production In A Cache Valley, Utah Farm Pond, J. Kent Summers May 1973

Primary Production In A Cache Valley, Utah Farm Pond, J. Kent Summers

All Graduate Theses and Dissertations

Primary production was measured on a 9.5 acre Cache Valley, Utah farm pond from July 1971 to July 1972. Polyethylene film tubes, with lids, were used to confine columns of water for determining dissolved oxygen concentration. Once a week, dissolved oxygen samples were taken at sunset, the following sunrise and sunset. Annual primary production was estimated at 1289 grams oxygen per square meter for two of the four stations, and 927 grams oxygen per square meter for the remaining two stations. The weekly data was computed at once a month intervals to see if it would be possible to ...


The Effects Of Elevation And Vegetation Type On Snow Accumulation And Melt In Logan Canyon, Utah, Paul R. Thies May 1973

The Effects Of Elevation And Vegetation Type On Snow Accumulation And Melt In Logan Canyon, Utah, Paul R. Thies

All Graduate Theses and Dissertations

Snow accumulation and melt characteristics were studied in Logan Canyon, Utah. Three replications of aspen, conifer, and open field types at 6300, 7100,and 8000 feet were measured for snow depth and water content during 1972. Elevation was found to have the greatest effect on snow water content. The gradient of increasing water content with rise ln elevation was found to be .51 inches/100 feet in the zone from 6300 to 7100 feet and 1.9 inches/100 feet from 7100 to 8000 feet. The cooler temperatures at higher elevations partially account for the 8000 foot zone beginning to ...


The Effects Of Available Water Upon Populations Of Chukar Partridge On Desert Mountains Of Utah, William W. Shaw May 1971

The Effects Of Available Water Upon Populations Of Chukar Partridge On Desert Mountains Of Utah, William W. Shaw

All Graduate Theses and Dissertations

The importance of surface water to chukar partridges (Alectoris graeca) and the feasibility of rain-catchment devices for improving chukar habitat were studied on the Thomas and Dugway Mountain Ranges in western Utah during 1969 and 1970.

Sources of surface water were removed from one mountain rang~ and chukar populations on that range were compared with populations on an adjacent range with permanent sources of water.

Providing drinking water did not improve chukar productivity, survival, or availability to hunters. Although most birds concentrated around water supplies in the summer, some chukars appeared to live completely independent of any permanent sources of ...


Seasonal Utilization Of Sago Pondweed By Waterfowl At Bear River Migratory Bird Refuge, Utah, Michael R. Sterling May 1970

Seasonal Utilization Of Sago Pondweed By Waterfowl At Bear River Migratory Bird Refuge, Utah, Michael R. Sterling

All Graduate Theses and Dissertations

Seasonal utilization of sago pondweed (Potamogeton pectinatus L.) by waterfowl was studied at Bear River Miqratory Bird Refuge by comparing amounts of sago production on a series of plots on Unit Four. One plot was available to carp and waterfowl; one only to carp; and one available to neither.

The cage used to eliminate carp and waterfowl use of a plot caused a significant increase in sago production. The increase was attributed to less turbidity and less wind and wave action within the cage.

Carp distribution was limited to deep-water portions of Unit Four, a small area, and they had ...


An Evaluation Of Factors Affecting Establishment And Survival Of Russian Wildrye (Elymus Junceus Fisch.) On Foothill Ranges In Utah, Dale Lynn Drawe May 1970

An Evaluation Of Factors Affecting Establishment And Survival Of Russian Wildrye (Elymus Junceus Fisch.) On Foothill Ranges In Utah, Dale Lynn Drawe

All Graduate Theses and Dissertations

Russian wildrye (Elymus junceus Fisch.) is a longlived perennial bunchgrass introduced to this continent from Siberia by the University of Saskatchewan in 1926 (Lawrence and Heinrichs, 1966). It is now widely distributed throughout the Northern Great Plains and Intermountain area (Figure 1). The species does well in the Northern Great Plains, but even though it is recommended for foothill ranges in the Intermountain area (Plummer, et aI, 1955), there are problems with establishment of Russian wildrye in the Intermountain area. This study was an attempt to fill in some of the gaps in the knowledge about establishment and survival of ...


Farmers' Reactions Toward Upland Bird Hunting In Two Utah Counties, 1957, Frank J. Calkins May 1963

Farmers' Reactions Toward Upland Bird Hunting In Two Utah Counties, 1957, Frank J. Calkins

All Graduate Theses and Dissertations

Proof that public hunting on private lands is a growing Utah problem is, perhaps, most easily found by driving down any country lane. “No Trespassing" signs come one to a fence post or so it must seem to the pheasant hunter. His quarry is the most popular of Utah's farm game species and, unfortunately, the most popular subject of farmer-sportsmen disputes. Reasoning that short seasons reduce hunter nuisances and property damage, landowners have long advocated three to five day pheasant seasons. And because of this and a former game department concern about overshooting the birds (Utah Fish and Game ...


Studies In The Life History And Ecology Of The American Pintail (Anas Acuta Tzitzihoa Vieliot) In Utah, Robert W. Fuller May 1953

Studies In The Life History And Ecology Of The American Pintail (Anas Acuta Tzitzihoa Vieliot) In Utah, Robert W. Fuller

All Graduate Theses and Dissertations

Wildlife management has been defined as lithe manipulation of wild populations of vertebrate animals in their relation to man and his interests" Wildlife management, then, could not exist in the absence ot either wildlife or humans. Converting this idea to the waterfowl situation, we can say that there are no waterfowl problems other than as they exist in the minds of men. (Wil1s, 1951) These words by the Chief of the IllinoIs Natural History Survey precede a plea for fundamental facts and a basic understanding of waterfowl upon which sound management can in turn be based. l"or only through ...


The Status And Management Of Pheasant Posted Hunting Areas In Utah, William G. Parsons May 1953

The Status And Management Of Pheasant Posted Hunting Areas In Utah, William G. Parsons

All Graduate Theses and Dissertations

Since 1900 the ringneck pheasant Phasianus colchicus torquatus Gmelin has assumed major importance in the United states as an upland game bird. This is particularly evident in utah where, in 1951, 76,000 hunters bagged an estimated one quarter million pheasants (8). It is axiomatic that pheasant habitat in Utah is largely confined to land under irrigation. In Utah, this comprises onlY 2.2 percent of the total land area. These areas, essentially bottomlands along stream courses, are intensively farmed and generally assessed a high valuation per acre. Associated with intensive farming are population centers and resultant concentrations of hunters ...


Some Of The Relationships Between Livestock Grazing And Duck Nesting In The Saltgrass Vegetation Type In Utah, Horatio W. Murdy May 1953

Some Of The Relationships Between Livestock Grazing And Duck Nesting In The Saltgrass Vegetation Type In Utah, Horatio W. Murdy

All Graduate Theses and Dissertations

Little is known of the relationships between livestock grazlng and duck nesting. This dearth of information occurs in spite of the fact that an understanding of these relationshipships is necessary in order to evaluate duck production on range land, and to formulate grazing policies for lands devoted to the production of ducks. Recognizing the need for information on this subject, the Utah Cooperative Wlldllfe Research Unit and the Wildlife Management Institute jointly sponsored a study, during 1948-1949, of livestock grazing-duck nesting relationships in the saltgrass vegetation type in northern Utah. The study was financed by the Institute and supervised by ...


An Investigation Concerning The Incidence And Pathogenicity Of Pentatrichomonas Gallinarum And Its Relationship To Histomonas Meleagridis In Turkeys In Utah, Ross S. Hadfield May 1952

An Investigation Concerning The Incidence And Pathogenicity Of Pentatrichomonas Gallinarum And Its Relationship To Histomonas Meleagridis In Turkeys In Utah, Ross S. Hadfield

All Graduate Theses and Dissertations

Turkey raising has become big business. During the period 1942 to 1946, the average annual return in Utah amounted to about nine and one half million dollars (4). This amount would have been increased considerably if the death loss among poults had been lower. As an example, using the percentages of mortality given by Miner (9, P. 5), it is estimated that the death-loss of turkeys in 1944 resulted in a loss of gross income by the farmers of Utah of more than four million dollars provided that the price the farmer received had remained the same.


Utilization Of Forage Plants And Diet Of Sheep On Utah Winter Range, Lisle R. Green May 1948

Utilization Of Forage Plants And Diet Of Sheep On Utah Winter Range, Lisle R. Green

All Graduate Theses and Dissertations

Although there is an abudance of material available concering forage consumption by livestock on pasture land and in the feed lot, there is relatively little known about the grazing habits and forage preferences of livestock under range conditions. There has been still less scientific effort expended toward solving the riddle of the grazing animal's diet under winter range conditions. Investigators have suggested means to determine the quantity of forage available on range areas, the carrying capacities of range lands, and methods of determining the degree to which forage has been utilized. The diet of the foraging animal is affected ...
